Wind-energy long afterglow luminescence device

Abstract

A wind-energy long afterglow luminescence device comprises a casing (1), a wind power mechanical structure (2), a power generation device (3), LED luminous bodies (4) and a long afterglow luminous body (5); the power generation device (3) is connected with the wind power mechanical structure (2) and the LED luminous bodies (4) via lines respectively; and the wind power mechanical structure (2), driven by wind power, enables that the power generation device (3) drives the LED luminous bodies (4) to emit light and excites the long afterglow luminous body (5) to emit light. Power is used once being generated, the power transmission loss and using cost are reduced, the problem that a common wind energy luminescence device is hard to emit light continuously with minimal brightness without routine power supply or under a power off condition is solved, uninterrupted light emission is realized, and the minimal brightens of afterglow luminescence is improved greatly compared with a traditionallong afterglow luminescence; and a speed change mechanism can be used to improve the wind power generation efficiency further, a photovoltaic device can be combined, and wind and photovoltaic hybrid power supply is used to improve the safety of light emission.

Description

technical field [0001] The invention relates to the field of light emitting devices, in particular to a wind energy long afterglow light emitting device. Background technique [0002] In recent years, with the rapid development of society and economy, especially the progress of construction technology, the number of various underground buildings and underground transportation facilities such as: underground shopping malls, highway tunnels, subway tunnels, bridge culverts, etc. getting bigger. These places, especially some of the large-scale underground projects such as the Hong Kong-Zhuhai-Macao Bridge subsea tunnel, etc., are facing more and more needs for emergency lighting, security instructions and low-light lighting; and in such as: underground mines, underground air defense facilities Special lighting, emergency lighting, and escape indicating devices are also required in specific places such as weapons and ammunition depots to meet the rigid requirements of uninterru...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing light-emitting devices with better effects use mains power supply or partially use mains power supply, which has the following disadvantages: 1. Since the light-emitting devices in some places above require long-term uninterrupted light emission, it not only causes a large amount of power consumption, but also It is easy to cause line failure or device damage; 2. Due to the need to lay lines to connect to the city power grid, the cost of installation and maintenance is relatively high; 3. Because some of the above places are inconvenient to pull electricity or because the pull distance is too long, the cost is high , or it needs to be isolated from the mains grid for separate power supply to ensure the secondary lighting function, so this kind of lighting device cannot be used

How to meet the demand for secondary lighting protection in such places when the conventional power supply lighting system fails, especially the rigid demand for uninterrupted lighting has become a problem that has plagued the industry for many years, and there has been no better way to solve it
